[vtkusers] Modifying a point without creating the cells again

[Samuel Rodríguez Bescos]

Hello everybody,

I've a question about vtkPolyData:
Is it posible to modify one point position without updating the information
of the cells again?. I want to modify one point keeping the topological
information of the polydata and I haven't seen that it could be possible in
VTK.

Thanks in advance,

Sam
